CONDENSER FOR MOTOR-DRIVEN RAILWAY SECTION-CARS.

To all whom it may concern:

Be it known that I. GEoReE NVILsoN, citizen of the United States, residing at Albert Lea, in the county of Freeborn and State of Minnesota, have invented certain new and useful Improvements in Condensers for hlotor-Driven Railway Section-Cars, of which the following is a specification.

This invention relates to an improved condenser and radiator for motor driven railway section cars and has as its primary object to provide a device of this character for condensing the steam or vapor generated in the cooling hopper for the cylinder or cylinders of the car motor and returning the cooled water of condensation to the said hopper.

The invention has as a further object to provide a condenser embodying a relatively large area of radiating surface which will be exposed to the cooling influences of the air as the section car is propelled, for thus effectually condensing the steam from the cooling hopper of the car motor and cooling the alter of condensation to be returned to the said hopper.

A further object of the invention is to pro vide a condenser which may be embodied in the structure of the section car without the necessity for structural change therein and wherein the cooling pan or chamber of the condenser will be supported beneath the seat of the car to be housed and protected thereby.

And the invention has as a still further object to provide a construction wherein the cooling pan or chamber of the condenser will be mounted and connected with the cooling hopper of the car motor so as not to interfere with the usual sliding adjustment of the motor for tightening the motor drive belt.

Other and incidental objects will appear as the description proceeds. In the drawings wherein I have illustrated the preferred embodiment of the invention, and wherein similar reference characters designate corresponding parts throughout the several views:

In order that the construction mounting and operation of my improved condenser may be accurately understood, I have, in the drawings, shown said condenser in connection with a conventional type of motor driven railway section car. Referring more particularly to Fig. 1, it will be seen that this car includes the usual frame 10 to which are connected the car wheels 11. Rising from the frame are pairs of spaced seat standards or posts 12 which support the forward section 13 of the car seat. The rear section of the seat is indicated at 1%. One

end of this latter section is hinged to the forward section 13 and at its opposite end is equipped with spaced posts 15 for normally supporting the rear section to aline with the forward section. Slidably supported in the usual manner from the frame 10 is a car motor conventionally indicated at 16 and connected with this motor is a hand lever 17 for slidably adjusting the motor longitudinally with respect to the car frame. The motor 16 shown of the single cylinder type, being provided with a horizontally arranged cylinder 18. Surrounding this cylinder is a suitable water jacket therefor and upstanding from the said cylinder to communicate with the jacket is a cooling hopper 19 adapted to receive a supply of water for maintaining the cylinder of the engine cool. Section ear motors are, as is well known,

usually equipped with these cooling hoppers in lieu of a radiator, owing to the consequent reduction in cost as well as the lessening of the tendency of the body of water in the hopper to freeze in cold weather. Connected with the drive shaft of the motor is a drive pulley 20 and trained about this pulley and a Suitable pulley indicated in dotted linesat 21 upon the front axle of the car, is a drive belt 22 for propelling the car from the motor. As will be seen, this belt may be adjustably-tensioned by slidably adjusting the motor with respect to the frame 10 of the canthrough operation of the hand lever 17. Also, it is to be observed that access to the motor may be easily had by swinging-the rear section H'of the seat forwardly to rest upon the forward section of the said. seat.

Coming now more particularly to the subject of the present invention I employ a relatively long and shallow closed cooling pan or chamber 23 which is of a width to be freely received between the pairs of side standards 12 and is of a length toJeXtend throughout the length of the forward section 13 of the car seat therebeneath. Swingingly. .connectcd in any approved manner with the pan adjacent its forward end,- is a pair of links 24 provided at their lower ends with suitable loops receiving a pivot rod 25 therethrough. This pivot rod is arranged to extend between the foremost pair of uprights 12 to connect and bracethe uprights of said pair with respect to each other. -.Swingingly connected in any approved manner with the pan adjacent its rear extremity, is a similar pair of links 26 provided at their lower ends with suitable loops loosely receiving a pivot rod 27 therethrough. This pivot rod is arranged to extend between the rearmost pair of the uprights 12 to connect and brace the uprights of this. latter pair with respect to each other. The pan will thus be supported by the pairs of links 2st and 26 to rock upon the said pivot rods beneath the forward section 18 of tlie seat and in this connection it is to be observed that the pan is mounted in a position out of the way while at the same time, thesaid pan will be housed and protected beneath-theseat. Possibility of accidental injury tojthepan will thus be reduced to a minimum. Furthermore, no structural change in the seat is required in order to accomniodatethe pan.

Upstanding from the pan .adjacentqits forward end is a vent pipe 28 projecting loosely through a suitable slot in theseat sectionl3 and extending fromthe rearend ,ofthe pan in a planetherewith is a nipple or short section ofpipe 29. Threaded into theforward side of the hopper 19 of the car motor 16 at a point above the normal water evel in the said hopper, is a similar short section of pipe 30, and uniting these pipe .cooling chamber.

ber to; becondensed therein whence the water of condensation will gravitate back into the hopper' for cooling the body of .Watercontained therein. Inthis connection it will be noted, as best shown in Fig. 1,

that the pivot rod 27 .is located in a plane slightly below the pivot rod 25. The cooling chamber is thus inclined longitudinally from its forward end toward its rear end in the direction of the hopper so that as the steam or vapor is condensed in the cooling chamber, the water of condensation will immediately fiow backinto the hopper. Furt hermore, thisconstruction provides an arrangement. whereby the flat side faces of the cooling chamber will be presented at an angle to the plane of movement of the ,car. Lonseqnently, when the ear is in motion, currents of air will be caused to impinge against the side faces of the cooling iehamber for. effectually carrying off heat from the,steam or vapor therein and consequently quickly condensing such steam or vapor to be returned at a comparatively low temperature to the engine hopper. 'This effect is greatly enhanced by the fact that thecooling chamberis shallow and has wide side walls so that a correspondingly large .cooling area is presented to the influence of the currentsof airstriking against the r I. accordingly provide a construction whereby the water in the engineahopper will under ordinary circumstances, be prevented from overheating to maintain the cylinder of the mot-or properly cooled. In order to guard against any danger which would be incidentto banklng up of steam inthe cooling chamber, the vent 2 8 isprovided.

,A ttention is now directed tothe fact that since the cooling -chamber or pan 23 is mounted to rock upon the seat standards 15?, themotor lfi may, by manipulating the hand lever 17 as previously indicated, be shifted upon the can frame for eithertightening or loosening the drive, belt 22. Thus the presence-of my. improved condenserupon the car willtnotin the least interfere with the. usual adjustment of the car motor for regulating the tension of. the drive'belt and, furthermore, it will be seenthat adjustment of the-belt be had without likelihood of impairing the connectionbetween thecooling chamber or pan ofthe condenser and the cooling hopper of the engine motor.

.In Figsr3 and f of the drawings I have illustrated a. slight-modification in the invention which relates more particularly to the mounting of thecooling chamber or pan' municating with the jacket of this cylinder is a hopper '33. A- cooling chamber or pan is indicated at 34. This pan is substantially identical with the pan of the preferred construction with the exception that the vent therefor is arranged at the rear of the pan.

The Jan is as shown in Fi 4 mounted in rearwardly tilted position between the-pairs of standards of the forward section of the seat of the car, these standardsbeing conventionallyindicated at 35. Connected with opposite ends of the pan and extending through these standards are brace rods 36 rigidly securing the pan in position thereon. Leading to the forward end of the pan is an inlet pipe 37 which projects rearwardly from the pan toward the engine hopper and is provided with an elbow 38. A pipe 39 leads from the upper end of the hopper to form an elbow 4O alining with theelbow 38. Uniting these'elbows is a hose connection 41. Leading from the rear end ofthe pan or chamber 34-is a pipe 42-which extends rearwardly toward the engine hopper and is provided with an elbow 43. Communicating with the bottom of the water jacket of the cylinder 32 is a pipe 44 which extends upwardly at the adjacent side of the cylinder and thence forwardly "and is provided with an elbow 45 alining with the elbow 43. Uniting these elbows is a hose connection 46. Thus it will be seen that steam from the hopper 33 will-be directed intothe pipe 37 and carried thereby into the cooling chamber 34 at its forward end while the water of condensation will flow back through the cooling chamber to enter the return pipe 42 and be introduced into the water jacket of the motor cylinder at the point where the water in the jacket of the said cylinder will be the hottest. The cooled water of condensation will thus greatly tend to maintain the water in the bottom of the water jacket at a temperature corresponding to the body of water in the hopper. This modified construction, therefore, provides a very effective arrangement and it will be noted that since the hose connections 41 and 46 are arranged in a plane at right angles to the plane of adjustment of the car motor, this hose connection will flex when the motor is adjusted for regulating the tension of the drive belt of the car so that it accordingly becomes unnecessary to swingingly mount the cooling chamber or pan 34.

In Figs. 5 and 6 of the drawings, I have illustrated a still further modification of the invention. In these figures, the car motor is indicated at 47 and the cylinder of the motor at 48. Communicating with the water jacket of this cylinder is a hopper 49. Mounted to swing between-the uprights of the car seat as in the preferred construction, is a cooling chamber or pan 50. This pan is identical with the pan of the preferred embodiment of the invention with the exception that a vent 51 for theipan is arranged at the rear end thereof. Leading to the forward end of the pan is an. inlet pipe 52 connected to branch pipes 53 entering the pan adjacent its opposite side edges. Projecting forwardly from the upper extremity of the hopper 49 is a pipe 54 which extends within the hopper and is connected with a pump conventionally illustrated at 55, this pump, being preferably located within the hopper to avoid freezing. Uniting the pipes 52 and 54 is a hose connection 56. Leading from the rear end of the coolingchamber is a return pipe 57. A pipe 58 corresponding to the pipe 44 of the prior modification is connected with the water jacket of the motor cylinder 48 at the bottom side of the said jacket and extends forwardly from the hopper 49 in alinement with the 'pipe 57. Uniting these pipes is a hose connection 59. As will be seen, the motor may thus be slidably adusted for tensioning the drive belt thereof as in the preferred construction. Journaled in any approved mannerupon the hopper 49 is a suit.- able drive shaft 60 carrying a drive pulley 61. Connected with the drive shaft of the motor 47 is a pulley 62 and trained over these drive pulleys is a belt 63. 'It will accordingly be clear that when the motor is in operation, the pump 55 will act to force water from the hopper 49 into the cooling chamber or pan 50 to maintain a constant circulation of water through the said chamberfor effectually maintaining the cylinder of the motor cooled. Under particular working conditions such, for instance, as when the condenser is to be used in connec tion with a section car employed in hilly country so that the motor will accordingly be subjected to severe work, this present modification of the invention will be found particularly advantageous.

In Fig. 7 of the drawings I have illustrated a still further modification of the invention. In this figure the cooling chamber or pan of the condenser is indicated at 64. This pan is identical with the pan disclosed in the prior modification and is mounted in a similar manner. The hopper of the car motor is indicated at 65. Extending through the forward end of the pan is a pipe 66 corresponding to the pipe 52 of the prior modification and connected with branch pipes 67 entering the pan adjacent its opposite side edges. Leading from the upper end of the hopper is a pipe 68 alining with the pipe 66 and connecting these pipes is a hose connection 69. Leading from the bottom side of the water jacket of the motor is a pipe 70 corresponding=to thepipe '58- of the-prior: modification but 1 extending at the I oppositeside of the motor cylinder. 1 -A return pipe 71' extends from the rear-end of the coolingqoan and is united with the pipe =70by a hoseconnection '79. As: will be seen, the present modification discloses a simple manner of" connecting the cooling" pan or cliamber withthe motor Without the use of 1 a circulating pump asinwthe priormodi fication;

In Fig.8 I have shown a .slightlymodified form or cooling pan OI ChZLmbGI.
